Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0035] This embodiment relates to a dent repair puller, as shown in the following figure. Figures 1-4 The device includes a puller body 100, a puller component 200, and support feet 300. One end of the puller component 200 passes through the puller body 100 and protrudes from the bottom side of the puller body 100. Support feet 300 are mounted on the bottom side of the puller body 100; two sets of support feet 300 are provided, located on either side of the end of the puller component 200 protruding from the bottom side of the puller body 100; each set of support feet 300 has at least two feet arranged side-by-side facing away from the puller component 200. Specifically, the arrangement of at least two support feet 300 in each set facing away from the puller component 200 provides more support points compared to traditional pullers, and the greater distance between the two sets of support feet 300 allows for the repair of wider depressions and expands the repair area. When the dent is narrow, the user can select the support leg 300 closer to the puller 200 from the two sets for quick repair. Conversely, when the dent is wide, the user can select the support leg 300 further from the puller 200 to ensure the puller 200 covers a wider area during removal. This avoids the problem of traditional pullers where the small distance between support legs limits the repair width, requiring multiple local repairs, resulting in higher repair efficiency. This dent repair puller has the advantage of repairing dents of varying widths and greater adaptability.

[0036] Furthermore, the support feet 300 in each group are spaced apart to provide sufficient space for installing the shims 710 that mate with the support feet 300. Multiple shims 710 are provided and are detachably mounted on the underside of the support feet 300, serving to protect the vehicle body surface.

[0037] In this embodiment, refer to Figures 4-6 The drawing component 200 includes a pull rod 210 and a drawing part 220. One end of the pull rod 210 is placed inside the top of the drawing device body 100, and the other end passes through the drawing device body 100 and protrudes from its bottom side. The drawing part 220 is detachably mounted on the bottom end of the pull rod 210 to facilitate replacement of different drawing parts 220. Specifically, the drawing part 220 has a slot 221, and one end of the drawing head is engaged within the slot 221. The slot 221 is designed to accommodate different drawing heads according to the shape and size of the actual recess, making operation more convenient.

[0038] Furthermore, the puller body 100 includes a main body 110 and a puller seat 120. The main body 110 has a first through hole 111 at its top and a first channel 112 communicating with the first through hole 111. The puller seat 120 is rotatably mounted on the bottom of the main body 110, and has a second channel 121 communicating with the first channel 112. The first channel 112 and the second channel 121 are used for the pull rod 210 to pass through. Compared to traditional one-piece pullers, the puller seat 120 in this dent repair puller is rotatably mounted on the main body 110, allowing for flexible adjustment of the support position of the support foot 300, making operation more convenient. The first through hole 111, the first channel 112, and the second channel 121 are all vertically arranged on the same axis, allowing the pull rod 210 and the puller part 220 to move vertically up and down, ensuring the repair effect.

[0039] In this embodiment, refer to Figures 5-8The main body 110 has a first groove 113 on the side facing the puller 120; the puller 120 has multiple second grooves 122 arranged circumferentially on the side facing the main body 110. This dent repair puller also includes: a ball bearing 410 placed between the first groove 113 and the second grooves 122, and a first elastic reset member 420 with one end abutting against the inner wall of the first groove 113 and the other end abutting against the ball bearing 410. The first elastic reset member 420 uses its elasticity to press the ball bearing 410 into the second groove 122, achieving locking and limiting. During use, the force applied by the user to rotate the puller 120 must be greater than the force exerted by the first elastic reset member 420 on the ball bearing 410, so that the ball bearing 410 can disengage from the current second groove 122 and roll to the next second groove 122. The user can clearly feel a "sticking" sensation while rotating the puller 120; each time it passes through a second groove 122, the ball bearing 410 bounces once, forming a clear positioning position. The engagement of the first elastic reset member 420, the ball bearing 410, the first groove 113, and the second groove 122 ensures smooth rotation between the pull-out seat 120 and the main body seat 110 while preventing angular displacement of the pull-out seat 120 due to external vibration or impact. In this embodiment, the first elastic reset member 420 is a spring. In some embodiments, the first elastic reset member 420 can also be a spring sheet or other components with elastic reset structures.

[0040] Furthermore, multiple first grooves 113 are provided. Correspondingly, multiple first elastic reset members 420 and ball bearings 410 are also provided. Specifically, in this embodiment, four first grooves 113 are provided, and four first elastic reset members 420 and four ball bearings 410 are also provided. In some embodiments, six first grooves 113, six first elastic reset members 420, and six ball bearings 410 may also be provided.

[0041] In this embodiment, refer to Figures 5-8This dent repair puller also includes: a handle 510, a first sleeve 520, a grip 530, and a second sleeve 540. One end of the handle 510 is fixedly mounted on the top side wall of the main body 110, and the other end extends outward. The first sleeve 520 is fixedly sleeved on the top of the pull rod 210; the first sleeve 520 is located between the pull rod 210 and the main body 110. One end of the grip 530 is hinged inside the main body 110, and the other end extends outside the main body 110 and is located below the handle 510; the grip 530 has a second through hole 531 communicating with the first channel 112 and the second channel 121. The second sleeve 540 is fitted onto the pull rod 210; the top side of the second sleeve 540 abuts against the bottom side of the first sleeve 520, and the bottom side of the second sleeve 540 abuts against the handle 530; the main body 110 has a movable cavity 114 for one end of the handle 530 to move; one side of the movable cavity 114 communicates with the outside so that the other end of the handle 530 can extend out. During use, the user assembles the pull head adapted to the dent on the pulling part 220, and simply pulls the handle 530 towards the handle 510. The end of the handle 530 hinged in the main body 110 pushes the second sleeve 540 upward, which in turn pushes the first sleeve 520 upward. The first sleeve 520 drives the pull rod 210 upward, and finally the pull rod 210 drives the pulling part 220 upward, thus achieving the purpose of repairing the dent. This dent repair puller is easy to operate and portable. In some embodiments, the dent repair puller further includes an adjusting nut 720 mounted on the top of the pull rod 210 and located between the first sleeve 520 and the main body seat 110. The adjusting nut 720 is used to control the upward displacement of the pull section 220 by adjusting the pull rod 210, so as to better perform the repair work.

[0042] Furthermore, this dent repair puller also includes a second elastic reset member 600 sleeved on the outer side of the bottom end of the pull rod 210. One end of the second elastic reset member 600 abuts against the pull seat 120, and the other end abuts against the pull portion 220. During the upward movement of the pull rod 210 and the pull portion 220 by pulling the grip 530 upwards, the second elastic reset member 600 is gradually compressed. After releasing the grip 530, the grip 530, pull rod 210, and pull portion 220 return to their original positions under the restoring force of the second elastic reset member 600, facilitating the next pulling operation. In this embodiment, the second elastic reset member 600 is a spring. In some embodiments, the second elastic reset member 600 may also be a spring sheet or other components with an elastic reset structure.

[0043] Furthermore, referring to Figures 4-6The pull-out seat 120 has a mounting groove 123 on the side facing the pull-out part 220 for inserting one end of the second elastic reset member 600. A third through hole 1231 communicating with the second channel 121 is provided on the inner wall of the mounting groove 123, so that the pull rod 210 can move smoothly upwards or downwards. Specifically, one end of the second elastic reset member 600 abuts against the inner wall of the mounting groove 123, and the other end abuts against the pull-out part 220. The mounting groove 123 is used to limit the movement of the second elastic reset member 600, preventing it from shifting during use and affecting the reset of components such as the pull rod 210 and the pull-out head.

[0044] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
