A rack 5 is vertically fixed on the outer side wall of the movable rod 3, an illuminating lamp 4 is arranged at the top of the movable rod 3, and a lampshade is fixedly connected to the outer surface of the illuminating lamp 4 to protect the illuminating lamp 4; when the movable rod 3 moves downwards, the illuminating lamp 4 is driven to move downwards and returns to the inside of the box body 1, at the moment, the illuminating lamp 4 can be protected from being damaged in the carrying process, and the work of excavating a tunnel can be smoothly carried out.

Rotate on the inner wall of dead slot 2 and install first pivot 8, the lateral wall that the box was seen through to the one end of first pivot 8 outwards extends, the tip fixedly connected with turning handle 19 of outwards extending, it is rotatory to conveniently operate first pivot 8 through turning handle 19, fixed mounting has first gear 10 and ratchet 15 on the shaft part that is located dead slot 2 of first pivot 8, it is connected with second pivot 9 still to rotate on the inner wall of dead slot 2, fixed mounting has second gear 11 and third gear 12 in the second pivot 9, first gear 10 and third gear 12 mesh, the rack 5 meshing on second gear 11 and the 3 lateral walls of carriage release lever.

The limiting groove 21 has been seted up on the lateral wall of box 1, it is connected with third pivot 13 to rotate on the inner wall of limiting groove 21, third pivot 13 all is parallel to each other with first pivot 8 and second pivot 9, install connecting rod 14 on the third pivot 13, the inner of connecting rod 14 stretches into ratchet 15 department and fixedly connected with ratchet 16, ratchet 15 cooperates with ratchet 16, the other end of connecting rod 14 passes limiting groove 21 and extends to the external world, still fixedly connected with stopper 17 of the inner upside of connecting rod 14, the top fixedly connected with reset spring 18 of stopper 17, reset spring 18's top fixed connection is on the interior roof of box 1, make ratchet 16 and ratchet 15 keep elastic contact through reset spring 18.

The bottom of the box body 1 is fixedly connected with a first fixed block 22 and two rollers 23, the first fixed block 22 and the two rollers 23 are symmetrically distributed, and the lower surfaces of the first fixed block 22 and the rollers 23 are on the same horizontal line; fixed connection pulling handle 20 on the lateral wall of the gyro wheel 23 one side of box 1, when carrying out excavation work, when the position of light 4 need be removed, only need pulling handle 20, through 23 rounds of gyro wheels, move suitable positions to box 1 on, not only effectual save time has still improved work efficiency simultaneously for the progress of excavation tunnel work.

Furthermore, the outer surfaces of the pulling handle 20 and the rotating handle 19 are both provided with anti-skid rubber pads, so that the friction force is increased, and the stress is uniform.

Example two

The working principle is as follows: when a worker wants to perform tunnel excavation work, the worker firstly rotates the rotating handle 19 clockwise to drive the first rotating shaft 8 to rotate, so that the first gear 10 and the ratchet wheel 15 rotate, the ratchet wheel 15 does not normally rotate under the influence of the ratchet 16 when rotating clockwise, the ratchet 16 is clamped with teeth of the ratchet wheel 15 and cannot rotate anticlockwise, so that the first rotating shaft 8 can only rotate clockwise, the first gear 10 is meshed with the third gear 12, so the first gear 10 drives the third gear 12 to rotate, when the third gear 12 rotates, the second rotating shaft 9 is driven to rotate, so the second gear 11 is driven to rotate, and because the second gear 11 is meshed with the rack 5, the moving rod 3 is driven to move upwards to push the illuminating lamp 4 to move upwards, when the rotating handle 19 is stopped and loosened, the moving rod 3 does not move upwards any more, the illuminating lamp 4 has an effective illuminating effect at a high place, and then performing excavation work.

When the illuminating lamp 4 needs to be moved, the box body 1 is slightly inclined by pulling the pulling handle 20, the first fixing block 22 is separated from the ground, the roller 23 rotates on the ground and moves towards the destination, when the destination is reached, the box body 1 is swung to be right, the lower surface of the first fixing block 22 is abutted against the ground, when the excavating work is finished, the outer end part of the connecting rod 14 is pressed downwards at first, the connecting rod 14 rotates on the third rotating shaft 13, the inner end of the connecting rod 14 rotates upwards, the ratchet 16 is separated from the ratchet 15 upwards, at the moment, the rotating handle 19 is rotated anticlockwise, the first rotating shaft 8 rotates to drive the first gear 10 and the ratchet 15 to rotate, the third gear 12 is driven to rotate, the second rotating shaft 9 rotates to drive the second gear 11 to rotate, and the moving rod 3 moves downwards because the second gear 11 is meshed with the rack 5, the illuminating lamp 4 is driven to move downwards and return to the inside of the box body 1, at the moment, the rotating handle 19 is stopped and loosened, meanwhile, the connecting rod 14 is loosened, the return spring 18 rebounds, the limiting block 17 is pushed downwards, and the ratchet 16 returns to the initial position to be attached to the teeth of the ratchet wheel 15.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

The invention has been described above by way of example, and it should be noted that any simple variants, modifications or other equivalent substitutions by a person skilled in the art without spending creative effort may fall within the scope of protection of the present invention without departing from the core of the present invention.
