[0046] The use principle of this utility model:

[0047] like Figure 1The user presses the pressing head of the spring piece 44, holds the handle 6 and pulls out the U-shaped pull rod 42. When the U-shaped pull rod 42 reaches the circular groove on the side of the sleeve 41 that the user thinks is convenient to carry, the user pulls the U-shaped pull rod 42 until the pressing head of the spring piece 44 is engaged in the circular groove on the side of the sleeve 41. The user holds the handle 6 and, with the assistance of the universal wheel 5, pulls the entire device to the construction site, finds the position where a hole needs to be punched, retracts the U-shaped pull rod 42 to its original position, and places the entire device against the wall at the hole position in the direction away from the punching mechanism 3 according to the side of the hydraulic support assembly 1, locks the universal wheel 5, and removes the two limit bolts 43 fixed by bolts on the sides of the two sleeves 41 close to the hydraulic support assembly 1. At this time, because there is no support from the limit bolts 43 And because of the gravity exerted on the whole device, the non-folding support mechanism 4 of the device will use the universal wheel 5 in the locked state as the rotation base point, and tilt in the direction in which the hydraulic support assembly 1 is away from the punching mechanism, until the hinged joint of the hydraulic support assembly 1 and the bottom plate 2 replaces the top end of the handle 6 to support the whole device on the wall. At the same time, in this process, the folding support mechanism 4 will automatically tilt toward the punching mechanism 3 because the sleeve 41 and the bottom end of the telescopic part of the hydraulic support assembly 1 are hinged on both sides, and if it does not tilt, the user can pull the handle 6 in that direction to pull the folding support mechanism 4 in that direction with the hinged joints of the sleeve 41 and the bottom end of the telescopic part of the hydraulic support assembly 1 as the rotation base point, so that the folding support mechanism 4 rotates until When the hydraulic support assembly 1 contacts the ground, the telescopic part of the hydraulic support assembly 1 is raised to raise the device, and the folding support mechanism 4 is unfolded while raising it. The support rod 45 and the hydraulic support assembly 1 are hinged in a form that stably supports the entire device through the clamping connection between the spring piece 44 and the circular groove of the sleeve 41 and the clamping connection between the pull bolt 46 in the end of the support rod 45 away from the sleeve 41 and the exposed circular groove of the protruding part of the hydraulic support assembly 1. At this time, the support can be adjusted by adjusting the clamping level of the spring piece 44 and the circular groove of the sleeve 41 and the hinge angle of the support rod 45 and the hydraulic support assembly 1. The hydraulic support assembly 1 leaning against the wall is straightened, and the unfolded folding support mechanism 4 is adjusted so that it can be stabilized on the ground. The lock of the universal wheel 5 is opened, and the handle fixed on the end surface of the bottom plate 2 facing the ground is held. Use handle 7 to lift up the base plate 2 together with the entire punching mechanism 3, push the holding handle 7 to press the hydraulic support assembly 1 against the punching wall with the assistance of the universal wheel 5, adjust the punching height by lifting and lowering the hydraulic support assembly 1, and adjust the lifting and lowering while also adjusting the unfolded folding support mechanism 4 to provide a stable support, control the punching angle by the hinge connection between the base plate 2 and the hydraulic support assembly 1, control the punching depth by the extension and retraction of the hydraulic cylinder 34 in the punching mechanism, ensure the feasibility of punching by the power of the motor 32 to execute the drill bit 33 fixed at the end, complete the entire punching process by locking and releasing the universal wheel 5 to control the advancement and movement of the control device, and after the construction is completed, use the above-mentioned unfolding device process and the contracting device period to facilitate carrying, thereby allowing the conversion of multiple construction scenes.
