When the crowbars are subjected to excessive pressure and deformed, it is not convenient to replace them, and it is not easy to hold the crowbars.

[0010] To achieve the above purpose, the utility model provides the following technical solution: a crowbar for facilitating the installation of ALC partition boards, comprising:

[0011] A crowbar body, serving as a bearing base of the crowbar, one end of the crowbar body being connected to a crowbar plate;

[0012] A connecting hole is provided inside the upper part of the crowbar body, a handle is rotatably connected in the connecting hole, and a first bevel gear is fixedly connected to the handle;

[0013] A second bevel gear is meshed and connected above the first bevel gear, the second bevel gear is fixedly connected in a limit bearing, and the limit bearing is fixedly connected in the connecting hole;

[0014] A threaded rod is fixedly connected above the second bevel gear, an internal threaded tube is threadedly connected to the second bevel gear, a handle is fixedly connected to the top of the internal threaded tube, a slide is fixedly connected to one side of the internal threaded tube, the slide is slidably connected in a slide rail, and the slide rail is fixedly connected to the inner wall of the connecting hole.

[0015] Preferably, the first bevel gear, the second bevel gear, the threaded rod and the internal threaded tube form a linkage structure, and the height of the internal threaded tube is equal to the height of the slide plate, so that the internal threaded tube is restricted by the slide plate to prevent the internal threaded tube from rotating with the rotation of the threaded rod.

[0016] Preferably, the skid plate comprises:

[0017] A clamping plate, fixedly connected to the prying plate, the clamping plate is clamped and connected in a clamping slot, and the clamping slot is provided at one end of the crowbar body;

[0018] A screw rod is fixedly connected below the crowbar body, an internal threaded tube is threadedly connected to the screw rod, and the internal threaded tube is fixedly connected in a bearing. A cross plate is embedded and connected on one side of the bearing. By installing the cross plate between the two groups of screw rods, the clamping plate is blocked in the clamping groove, and then the crowbar plate is installed at one end of the crowbar body.

[0019] Preferably, the top-view cross-sectional shapes of the card plate and the card slot are both T-shaped, and there is an interference fit between the card plate and the card slot, and the length of the cross plate is greater than the length of the card slot, so that the cross plate can completely restrict the card plate and improve the structural stability.

[0020] Preferably, the handle comprises:

[0021] The protective cover is fixedly connected to the handle, the protective cover is provided with a gripping groove, and the gripping groove is provided with anti-skid patterns to increase friction and prevent separation.

[0023] Compared with the prior art, the utility model has the following beneficial effects: the crowbar for the installation of ALC partition boards can drive the threaded rod to rotate by rotating the handle, so that the internal threaded tube can slide in the connecting hole, thereby adjusting the overall length of the device, which is convenient for installing the ALC partition boards. The card plate is inserted into the card slot, and the cross plate is installed between the two sets of screw rods to lock the card plate in the card slot. When replacement is required, the internal threaded tube is rotated in the reverse direction to pull out the crowbar. The gripping groove is deformed by force to adapt to fingers of different sizes. At the same time, the anti-slip pattern contacts the gripping part to increase the friction, making it easier to grip.

[0024] 1. First, when in use, rotate the handle, the handle drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the threaded rod to rotate through the limit bearing. Since the threaded rod is threadedly connected in the internal threaded tube, and the internal threaded tube is slidably connected in the connecting hole through the slides and slide rails on both sides, the internal threaded tube will not rotate with the rotation of the threaded rod, but move outwards through the rotation force of the threaded rod, so that the length of the crowbar body can be adjusted as needed, so as to facilitate the installation of the ALC partition board;

[0025] 2. Before use, match the card plate with the card slot, and then push the card plate into the card slot to install the pry plate at one end of the crowbar body. Since the card plate and the card slot are both T-shaped, the pry plate will not fall downward. Then, the two sets of internal threaded barrels on the horizontal plate are matched with the two sets of screw rods at one end of the crowbar body. The internal threaded barrels are rotated through the bearings to make the horizontal plate fit on one end of the crowbar body, thereby blocking the card plate in the card slot. When the pry plate is deformed by force, the two sets of internal threaded barrels are rotated in the opposite direction to remove the horizontal plate, and the pry plate can be pulled out from the crowbar body, so that the pry plate is easy to replace;

[0026] 3. When in use, the hand is held in the gripping groove on the protective cover. Since the protective cover is made of rubber, the gripping groove is deformed by force to adapt to fingers of different sizes. At the same time, the anti-slip pattern contacts the gripping part to increase friction, making it easier to hold. BRIEF DESCRIPTION OF THE DRAWINGS

By rotating the handle 4, the threaded rod 7 is driven to rotate, so that the internal threaded tube 8 can slide in the connecting hole 3, thereby adjusting the overall length of the device, which is convenient for installing the ALC partition board.

[0033] The first bevel gear 5, the second bevel gear 6, the threaded rod 7 and the internal threaded tube 8 form a linkage structure, and the height of the internal threaded tube 8 is equal to the height of the slide plate 10, so that the internal threaded tube 8 is restricted by the slide plate 10 to prevent the internal threaded tube 8 from rotating with the rotation of the threaded rod 7.

[0034] The pry plate 2 includes: a clamping plate 12, which is fixedly connected to the pry plate 2, and the clamping plate 12 is clamped and connected in a clamping groove 13, and the clamping groove 13 is provided at one end of the crowbar body 1; a screw rod 14, which is fixedly connected to the bottom of the crowbar body 1, and an internal threaded tube 15 is threadedly connected to the screw rod 14, and the internal threaded tube 15 is fixedly connected in a bearing 16, and a cross plate 17 is embedded and connected on one side of the bearing 16. By installing the cross plate 17 between two groups of screw rods 14, the clamping plate 12 is blocked in the clamping groove 13, and then the pry plate 2 is installed at one end of the crowbar body 1. The top-view cross-sectional shape of the clamping plate 12 and the clamping groove 13 is T-shaped, and the clamping plate 12 and the clamping groove 13 are interference fit, and the length of the cross plate 17 is greater than the length of the clamping groove 13, so that the cross plate 17 can completely restrict the clamping plate 12 and improve the structural stability. The clamping plate 12 is clamped into the clamping slot 13, and the cross plate 17 is installed between the two sets of screw rods 14 to seal the clamping plate 12 in the clamping slot 13.

Five groups of gripping grooves 19 are arranged at equal distances on the protective sleeve 18, and the material of the protective sleeve 18 is rubber, and the anti-skid pattern 20 is spirally provided in the gripping groove 19, further increasing friction and making it easier to hold. The gripping groove 19 is deformed by force to adapt to fingers of different sizes, and the anti-skid pattern 20 is in contact with the gripping part to increase friction, making it easier to hold.

[0036] Working principle: Figure 1-3As shown, when using the crowbar for ALC partition board installation, a simple understanding of the device is made. First, when in use, rotate the handle 4, the handle 4 drives the first bevel gear 5 to rotate, the first bevel gear 5 drives the second bevel gear 6 to rotate, and the second bevel gear 6 drives the threaded rod 7 to rotate through the limit bearing 21. Since the threaded rod 7 is threadedly connected in the internal threaded tube 8, and the internal threaded tube 8 is slidably connected in the connecting hole 3 through the slides 10 and the slide rails 11 on both sides, the internal threaded tube 8 will not rotate with the rotation of the threaded rod 7, but will move outward through the rotation force of the threaded rod 7, so that the length of the crowbar body 1 can be adjusted as needed, so as to facilitate the installation of the ALC partition board. Secondly, before use, match the card plate 12 with the card slot 13, and then push the card plate 12 into the card slot 13, so that the crowbar plate 2 is installed at one end of the crowbar body 1. The card slots 13 are all T-shaped, so the prying plate 2 will not fall downward. Then, the two groups of internal threaded tubes 15 on the cross plate 17 correspond to the two groups of screw rods 14 at one end of the crowbar body 1, and the internal threaded tube 15 is rotated through the bearing 16 to make the cross plate 17 fit one end of the crowbar body 1, thereby blocking the card plate 12 in the card slot 13. When the prying plate 2 is deformed by force, the two groups of internal threaded tubes 15 are rotated in the opposite direction to remove the cross plate 17, so that the prying plate 2 can be pulled out from the crowbar body 1, thereby facilitating the replacement of the prying plate 2. Then, when in use, the hand is held in the gripping groove 19 opened on the protective cover 18. Since the material of the protective cover 18 is rubber, the gripping groove 19 is deformed by force to adapt to fingers of different sizes. At the same time, the anti-slip pattern 20 contacts the gripping part to increase the friction, making it easier to grip. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
