DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0029] This embodiment mainly describes the adjustable lighting structure of an electric hammer and pick that can adjust the front and rear positions of the lighting equipment to facilitate drilling observation, as follows:

[0030] like Figure 1-5As shown, the adjustable lighting structure of the electric hammer and electric pick comprises a main body 001 and a lighting device 002 slidably mounted on the main body 001 , and the lighting device 002 can be limited at the sliding position of the main body 001 .

[0031] In this embodiment, a slide 1 is provided directly above the main body 001. The slide 1 is provided with a connecting portion 11 connected to the main body 001, and a limiting portion 12 connected and arranged above the connecting portion 11. The connecting portion 11 is located between the limiting portion 12 and the main body 001.

[0032] The slide 1 is in a T-shaped structure or a dovetail-shaped structure with a larger upper portion and a smaller lower portion. Connecting portions 11 extend from the left and right sides of the limiting portion 12. A sliding groove 001a extending from front to back is formed between the limiting portion 12 and the main body 001. A plurality of limiting grooves 13 distributed front to back are provided on the upper end surface of the limiting portion 12. An opening is provided on the limiting groove 13. Preferably, the limiting groove 13 connects the left and right sides of the limiting portion 12.

[0033] like Figure 3 As shown, the lighting device 002 includes a connecting frame 2 that is slidably connected to the slide 1. The connecting frame 2 is provided with a slot 21 for the limiting portion 12 of the slide 1 to be inserted. The slot 21 is provided with an opening at the bottom, and the slot 21 is penetrated from front to back. Limiting edges 22 are provided on the groove walls on the left and right sides of the slot 21. When the connecting frame 2 is inserted into the slide 1 through the slot 21, the limiting portion 12 of the slide 1 is partially located in the slot 21 of the connecting frame 2, and the limiting edge 22 of the connecting frame 2 is located in the slide groove 001a. The limiting edge 22 of the connecting frame 2 cooperates with the limiting portion 12 of the slide 1 to limit the connecting frame 2 from detaching from the top of the slide 1.

[0034] like Figure 4 As shown, the lighting device 002 includes a flashlight 3 fixedly connected to the connecting frame 2. The flashlight 3 is arranged above the connecting frame 2. The connecting frame 2 and the flashlight 3 are fixedly connected by two screws 4. Two lower-opening limiting holes 23 are provided on the groove wall at the upper end of the slot 21 of the connecting frame 2. The screw 4 is inserted from the bottom of the connecting frame 2, and the nut 41 of the screw 4 falls into the limiting hole 23, and the screw 42 of the screw 4 is threadedly connected to the flashlight 3.

[0035] Preferably, the axial depth of the limiting hole 23 is greater than or equal to the thickness of the nut 41 of the screw 4, so that the nut 41 of the screw 4 can be completely hidden in the limiting hole 23. When the nut 41 of the screw 4 slides relative to the slide 1 on the connecting frame 2, i.e., the lighting device 002, there will be no interference between the nut 41 of the screw 4 and the upper end surface of the limiting portion 12 of the slide 1.

[0036] In this embodiment, two connecting columns 31 are provided at the lower end of the flashlight 3, and each connecting column 31 is provided with a threaded hole with a lower opening. The screw 42 of the screw 4 is threadedly connected to the threaded hole on the connecting column 31 one by one. The setting of the screw 4 makes the flashlight 3 and the connecting frame 2 detachable and installable. Preferably, the two connecting columns 31 are distributed front and back.

[0037] like Figure 3-5 As shown, the connecting frame 2 is provided with an upper opening mounting cavity 24, the outer wall of the flashlight 3 is an arc-shaped structure and blocks the cavity opening of the mounting cavity 24, and a limiting member 5 and two elastic members 6 are installed in the mounting cavity 24. The elastic member 6 is elastically supported between the flashlight 3 and the limiting member 5, and the limiting member 5 is partially exposed to the slot 21 of the slide 1 under the action of the elastic member 6.

[0038] Two sockets 51 are provided on the limiting member 5, and the elastic member 6 adopts a spring. One end of the elastic member 6 is inserted into the socket 51. A limiting plane 32 is provided on the outer wall of the flashlight 3 located in the installation cavity 24, and the other end of the elastic member 6 is supported on the limiting plane 32. The matching setting of the limiting plane 32 and the socket 51 can effectively prevent the elastic member 6 from shifting when the limiting member 5 is telescopic.

[0039] When the connecting frame 2 is slidably mounted on the slide 1 , the limiting member 5 can cooperate with any limiting groove 13 on the limiting portion 12 of the slide 1 to limit the sliding of the connecting frame 2 on the slide 1 .

[0040] In this embodiment, an effective opening 25 is opened on the connecting frame 2, and the effective opening 25 passes through the bottom of the installation cavity 24 of the connecting frame 2, and an insert section 52 is provided on the limiting member 5, and the insert section 52 is inserted into the effective opening 25, and the lower end of the insert section 52 extends to the slot 21 of the connecting frame 2, that is, the insert section 52 can be inserted into the limiting groove 13, and the end corners of the front and rear positions of the lower end of the insert section 52 and the end corners of the slots at the front and rear positions of the limiting groove 13 are chamfered. The chamfers can cooperate to enable the insert section 52 to move upward and disengage from the limiting groove 13, thereby facilitating the sliding adjustment of the connecting frame 2 on the slide 1.

[0041] In the present application, the lighting device 002 can slide on the main body 001 and can be installed in a limited position, so the front and rear positions of the lighting device 002 on the main body 001 can be adjusted, which is convenient for workers in a dim working environment. By adjusting the front and rear positions of the lighting device 002, the positions that need lighting can be better illuminated, that is, the drilling position and even the situation inside the hole after drilling can be better observed.
