[0003] 2. Description of the Related Art

[0004] A conventional hand tool, such as a wrench, a screwdriver or the like, can be used to operate a workpiece, such as a nut, bolt or the like. However, when the workpiece is located at a deeper or darker site, the user needs to hold a flashlight to provide an illumination effect during operation of the hand tool, thereby causing inconvenience to the user.

[0005] The primary objective of the present invention is to provide a lamp assembly that can be attached on a hand tool, such as a wrench, a screwdriver or the like, thereby providing an illumination effect.

[0006] Another objective of the present invention is to provide a lamp assembly, wherein the rotary body of the illumination device is swiveled about the positioning body of the positioning seat in a horizontal manner, so that the illumination device can be swiveled horizontally through 360 degrees so as to provide a horizontal illumination effect.

[0007] A further objective of the present invention is to provide a lamp assembly, wherein the rotary body of the illumination device is rotated about the positioning body of the positioning seat vertically, so that the illumination device can be rotated vertically so as to provide a vertical illumination effect.

[0008] A further objective of the present invention is to provide a lamp assembly that can be assembled and dismantled easily and conveniently.

[0009] A further objective of the present invention is to provide a lamp assembly, wherein the locking strip of the illumination device can be rotated with the rotary body and can be inserted into and locked in the locking groove of the positioning body.

[0010] In accordance with the present invention, there is provided a lamp assembly, comprising:

[0011] a positioning seat; and

[0012] an illumination device rotatably mounted on the positioning seat, so that an included angle between the illumination device and the positioning seat can be adjusted.

[0041] The rotary body 21 of the illumination device 11 is clamped by the locking blocks 33 of the positioning body 31 in an elastic manner.

[0042] The locking strip 22 of the illumination device 11 can be rotated with the rotary body 21 and can be inserted into and locked in the locking groove 32 of the positioning body 31.

[0043] The positioning board 20 of the illumination device 11 is formed with a dovetailed groove 24, and the support plate 10 has a dovetailed shape, so that the support plate 10 is secured in the dovetailed groove 24 of the positioning board 20.

[0044] The housing 12 of the illumination device 11 is provided with a bulb 13, a battery 131 (see FIG. 5), and a switch 14 (see FIG. 5).

[0045] As shown in FIG. 3, the attachment board 34 of the positioning seat 30 is attached on the handle 2 of a hand tool, such as a wrench 1 by the magnetic attraction effect of the magnetic body 35.

[0046] As shown in FIG. 4, the attachment board 34 of the positioning seat 30 is substantially inverted U-shaped and is rested on the two sides of the handle 2 of the wrench 1, so that the attachment board 34 of the positioning seat 30 is movable on the handle 2 of the wrench 1.

[0047] As shown in FIGS. 5 and 6, the rotary body 21 of the illumination device 11 is swiveled about the positioning body 31 of the positioning seat 30 horizontally, so that the illumination device 11 can be swiveled horizontally through 360 degrees so as to provide a horizontal illumination effect.

[0048] As shown in FIGS. 7-10, the rotary body 21 of the illumination device 11 is rotated about the positioning body 31 of the positioning seat 30 vertically, so that the illumination device 11 can be rotated vertically so as to provide a vertical illumination effect. In addition, the locking strip 22 of the illumination device 11 can be rotated with the rotary body 21 and can be inserted into and locked in the locking groove 32 of the positioning body 31.

[0049] Referring to FIG. 11, the attachment board 34 of the positioning seat 30 has a bottom formed with an arcuate locking body 40 that can be mounted on a circular handle. In addition, the magnetic body 35 is mounted between the attachment board 34 and the arcuate locking body 40.

[0050] Referring to FIGS. 12 and 13, the attachment board 34 of the positioning seat 30 has a bottom formed with a circular mounting body 41 that can be mounted on the circular shank 4 of a screwdriver 3.

[0051] Referring to FIG. 14, the attachment board 34 of the positioning seat 30 has a bottom formed with a substantially C-shaped elastic mounting body 42 that can be mounted on the circular shank of a screwdriver.

[0052] Referring to FIG. 15, the magnetic body 35 is mounted between the attachment board 34 and the circular mounting body 41.

[0053] Referring to FIG. 16, the magnetic body 35 is mounted between the attachment board 34 and the elastic mounting body 42.

[0054] Referring to FIGS. 17 and 18, the positioning board 20 of the illumination device 11 has two sides each provided with a plurality of locking teeth 25, and the support plate 10 has two sides each provided with a plurality of engaging teeth 15 engaged with the locking teeth 25 of the positioning board 20, so that the support plate 10 is secured on the positioning board 20.

[0055] Referring to FIGS. 19-21, each of the locking blocks 33 of the positioning seat 30 has an inner wall formed with an inner thread 45, and the rotary body 21 of the illumination device 11 has a periphery formed with an outer thread 44 screwed into the inner thread 45 of each of the locking blocks 33 of the positioning seat 30, so that the rotary body 21 of the illumination device 11 is retained on the positioning seat 30 without detachment.

[0056] Referring to FIG. 22, the attachment board 34 of the positioning seat 30 has a bottom provided with a pivot portion 46, and the positioning seat 30 further includes a clamping body 47 pivotally mounted on the pivot portion 46, and a torsion spring 48 urged between the pivot portion 46 and the clamping body 47. Thus, the positioning seat 30 can be attached on a user's waist belt.

[0057] Referring to FIG. 23, the attachment board 34 of the positioning seat 30 has a bottom provided with an elastic clip 49, so that the positioning seat 30 can be attached on a user's waist belt.
