[0002] Crowbars, widely used in hardware manufacturing and equipment maintenance, primarily utilize the lever principle and are frequently applied in various situations requiring prying, lifting, pushing, or flipping. However, when performing these actions, a fulcrum is required. Some crowbars have a straight end and a bent end. In situations where space is limited and the bent end cannot be used, only the straight end can be chosen. However, operating with the straight end requires relying on an external fulcrum for prying or lifting, which is inconvenient.
[0003] Therefore, existing technologies need further development. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an anti-slip pry bar to solve the technical problem in the related technology that when the space is narrow and the bendable head cannot be used, only the straight head can be selected. However, the operation of the straight head requires the use of an external fulcrum to pry or lift, which is inconvenient.
[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a non-slip pry bar is provided, comprising: a pry bar body, one end of which is provided with a straight pry head; a support component, which is movably disposed on the pry bar body and is disposed away from the straight pry head; wherein, when the straight pry head is required to perform a prying operation, the support component is moved to a suitable position and used as a first fulcrum or a second fulcrum to assist the pry bar body in prying up the target.
[0006] Furthermore, the support assembly includes: a support frame that extends along a preset trajectory and is movably mounted on the crowbar body along the extension direction of the crowbar body. The angle between the support frame and the crowbar body is greater than ° and less than °, and the support frame forms a first fulcrum or a second fulcrum.
[0007] Furthermore, the support frame includes: a first connecting plate, a second connecting plate, and a third connecting plate connected in sequence, the first connecting plate and the third connecting plate being arranged opposite to each other, the distance between the first connecting plate and the third connecting plate being greater than the width of the crowbar body, and the two ends of the second connecting plate being connected to the side of the first connecting plate and the third connecting plate away from the straight crowbar head, respectively.
[0008] Furthermore, corresponding sides of the crowbar body are provided with a first sliding groove and a second sliding groove extending along the extension direction of the crowbar body. Multiple limiting holes are spaced apart within both the first and second sliding grooves along the extension direction of the crowbar body, and these limiting holes extend along the width direction of the crowbar body. The support assembly also includes a first limiting post and a second limiting post, which are movably inserted into the first connecting plate and the third connecting plate respectively along the width direction of the crowbar body. When the support frame is fixed relative to the crowbar body, one end of the first limiting post passes through the first connecting plate and is inserted into any one of the multiple limiting holes in the first sliding groove; and one end of the second limiting post passes through the third connecting plate and is inserted into any one of the multiple limiting holes in the second sliding groove.
[0009] Furthermore, the support assembly also includes a support protrusion that extends along the width of the crowbar body and is mounted on the side of the second connecting plate away from the straight crowbar.
[0010] Furthermore, the crowbar also includes a reinforcing component, which is rotatably disposed on the side of the second connecting plate near the straight pry head, and the reinforcing component abuts against the crowbar body; wherein, when the reinforcing component abuts against the crowbar body, the reinforcing component, the crowbar body, and the second connecting plate form a triangular structure.
[0011] Furthermore, the reinforcing component includes: a reinforcing rod rotatably disposed on the second connecting plate; and an abutment plate mounted on the end of the reinforcing rod away from the second connecting plate.
[0012] Furthermore, the crowbar body has multiple toothed grooves, which are arranged sequentially along the extension direction of the crowbar body. The toothed grooves are located on the same side of the support frame, and the abutment plate engages with any one of the toothed grooves.
[0013] Furthermore, the other end of the crowbar body is equipped with a curved pry head. The straight pry head, the curved pry head and the crowbar body are designed as a single unit. Both the curved pry head and the straight pry head have wear-resistant and anti-slip teeth on their outer surfaces facing away from the support assembly.
[0014] Beneficial effects:

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0024] According to an embodiment of this utility model, a non-slip pry bar is provided. Please refer to [link / reference]. Figures 1 to 3 It includes: a crowbar body 1, with a straight pry head 2 at one end; a support assembly, which is movably mounted on the crowbar body 1 and is positioned away from the straight pry head 2; wherein, when the straight pry head 2 is needed to perform a prying operation, the support assembly is moved to a suitable position and used as a first fulcrum or a second fulcrum to assist the crowbar body 1 in prying up the target.
[0025] By adopting the above technical solution and through the design of the support component, when performing prying operations, the support component serves as the first or second fulcrum to assist the crowbar body 1 in prying up the target. This solves the problem that it is inconvenient to operate by relying on an external fulcrum to pry or lift when using a straight-head operation.
[0026] Please refer to Figure 1 The support assembly includes a support frame 3, which extends along a preset trajectory and is movably mounted on the crowbar body 1 along the extension direction of the crowbar body 1.

[0027] By adopting the above technical solution and through the design of the support frame 3, the position and angle of the support frame 3 can be adjusted during the process of supporting the crowbar body 1, thereby changing the magnitude of the force applied during the prying operation. By using the appropriate position and angle, the force applied during the prying operation can be reduced, thus helping workers save physical strength.
[0028] Please refer to Figure 3 The support frame 3 includes a first connecting plate 4, a second connecting plate 5, and a third connecting plate 6 connected in sequence.

[0032] Please refer to Figure 3 The support assembly also includes a support protrusion 9, which extends along the width of the crowbar body 1 and is mounted on the side of the second connecting plate 5 away from the straight crowbar 2.
[0033] By adopting the above technical solution and through the design of the support protrusion 9, the friction between the support protrusion 9 and the object being pried is increased during the prying operation, making it easier for workers to perform the prying operation.
[0034] Please refer to Figure 3 The crowbar also includes a reinforcing component, which is rotatably disposed on the side of the second connecting plate 5 near the straight pry head 2, and the reinforcing component abuts against the crowbar body 1; wherein, when the reinforcing component abuts against the crowbar body 1, the reinforcing component, the crowbar body 1 and the second connecting plate 5 form a triangular structure.
[0035] By adopting the above technical solution and strengthening the design of the components, during the process of prying up the target, the support of the components for the second connecting plate 5 is strengthened to form a stable triangular structure, thereby increasing the support strength of the support frame 3.
[0036] Please refer to Figure 3 The reinforcing assembly includes: a reinforcing rod 10, which is rotatably mounted on the second connecting plate 5; and an abutment plate 11, which is mounted on the end of the reinforcing rod 10 away from the second connecting plate 5.
[0037] By adopting the above technical solution and through the design of the abutment plate 11, it is easy to increase the contact area between the reinforcing rod 10 and the crowbar body 1, thereby increasing the stability of the reinforcing rod 10.
[0038] Please refer to Figure 1 The crowbar body 1 has multiple toothed grooves 12, which are arranged sequentially along the extension direction of the crowbar body 1. The toothed grooves 12 are located on the same side of the support frame 3, and the abutment plate 11 is engaged with any one of the toothed grooves 12.
[0039] By adopting the above technical solution and through the design of the toothed groove 12, the reinforcing rod's role in strengthening and stabilizing the support frame 3 is further enhanced.
[0040] Please refer to Figure 2 The other end of the crowbar body 1 is provided with a curved pry head. The straight pry head 2, the curved pry head and the crowbar body 1 are designed as a whole. Both the curved pry head and the straight pry head 2 are provided with wear-resistant and anti-slip teeth on the outer side of the support component facing away from each other.
