AI Technical Summary
The existing cross-rotary chuck pole has a small contact area with the inner side of the U-shaped groove and is unevenly subjected to stress, resulting in the chuck being unsolid and cannot be used with poles of different diameters, and is not flexible enough to use.
A new type of single-bar cross-rotary chuck is designed. Two sets of vertical U-shaped grooves are provided on the chuck body. The compression bolts are threaded to connect through the boss and the U-shaped groove. The center line and the right-angle bisector overlap to ensure that the top tightening force is applied evenly, and the support rod and the U-shaped groove are contacted by the inner wall, avoid tilt and fall off, and allow the vertical rod and the cross rod to change positions at will.
The support rod is uniformly in contact with the inner wall of the U-shaped groove, which enhances the stability of the chuck, avoids tilt and fall off, and improves the flexible use of the vertical rod and the cross rod.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental instruments, in particular to a novel single-rod cross chuck. Background Art
[0002] Cross-shaped chucks are widely used in laboratories to secure and support various experimental equipment due to their ease of operation and excellent stability. Currently, single-rod chucks available on the market typically come in two configurations: one employs a vertical cross-shaped fixation method, where a U-shaped slot is provided on the chuck, allowing bolts to be screwed into the chuck to directly tighten against the pole from the side. The other utilizes a fixed-size circular hole on the chuck, along with a through-slot connected to the hole. The chuck's slot size is adjusted using bolts to secure the pole.
[0003] The first method has an open cut-in entrance for the vertical pole, resulting in a small contact area between the vertical pole and the inner side of the U-shaped groove, resulting in uneven force, which can easily cause the chuck to be unstable or tilted and fall off. The other method has good stability while the round hole matches the size of the vertical pole. However, it cannot be used for vertical poles of different diameters, and the vertical poles cannot be flexibly replaced, making it inflexible and inconvenient to use. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the existing cross chuck vertical rod has a small contact area with the inner side of the U-shaped groove, the force is uneven, and the fixed round hole type chuck cannot be used on vertical rods with different diameters, which is not flexible and convenient to use.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention proposes a new type of single-rod cross-turn chuck, comprising a chuck body and a support rod fixed to the chuck body, the support rod comprising a vertical rod and a horizontal rod, the chuck body is provided with two groups of U-shaped grooves, the two groups of the U-shaped grooves are located on both sides of the chuck body, the two groups of the U-shaped grooves are arranged perpendicular to each other, the chuck body is also provided with two groups of clamping bolts, the clamping bolts pass through and are connected to the chuck body by threads, the two groups of the clamping bolts are respectively arranged corresponding to the two groups of U-shaped grooves, the vertical rod and the horizontal rod are respectively slidably arranged in the two groups of U-shaped grooves, and one end of the two groups of clamping bolts are respectively pressed and fixed to the vertical rod and the horizontal rod.
[0006] Preferred technical solution 1: The chuck body is provided with a boss at an angle at the position of the U-shaped groove, and the clamping bolt passes through the boss and is threadedly connected to the boss.
[0007] Preferred technical solution two: the bottom wall and side walls of the U-shaped groove are arranged vertically, the support rod is in contact with the bottom wall and side walls of the U-shaped groove respectively, and the center line of the clamping bolt coincides with the right-angle bisector of the U-shaped groove, ensuring that the tightening force of the clamping bolt is evenly applied to the support rod, so that the support rod is in contact with the bottom wall and side walls of the U-shaped groove, increasing the stability of the chuck connection and avoiding tilting and falling off.
[0008] Preferred technical solution three: A bolt handle is installed at the other end of the tightening bolt to facilitate rotation operation.
[0009] The utility model proposes a new type of single-rod cross-turn chuck, which has the following beneficial effects by adopting the above structure:
[0010] (1) Two sets of U-shaped grooves are provided on the chuck body for fixing the vertical rod and the horizontal rod. The center line of the clamping bolt installed on the boss coincides with the right angle bisector of the U-shaped groove, ensuring that the tightening force of the clamping bolt is evenly applied to the support rod, so that the support rod contacts the bottom wall and side wall of the U-shaped groove, thereby increasing the stability of the chuck connection and preventing tilting and falling off;
[0011] (2) The chuck body is provided with double U-shaped grooves. The two sets of U-shaped grooves are located on both sides of the chuck body and are arranged perpendicular to each other. When using, there is no need to consider the position of the vertical rod and the horizontal rod hole. The position of the vertical rod and the horizontal rod can be changed at will, which increases the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS
