Description of the invention: [Technical field of the invention] The present invention relates to a type of rear end carrier-carrying ball-type clamp pressing device, which is a type of carrier ball that is fastened to the trailer ball at the rear end of the vehicle. A bonding device, especially a pressing device on the bonding device, has a function of ensuring that the carrier frame is not deflected. * [Previous technology] ' Press, modern people pay more and more attention to leisure activities. The most popular is to ride the bicycle # activity, and even many tourist attractions in China have added bicycle lanes to provide public use. Therefore, the industry has developed many styles. The carrying frame allows the car to carry the bicycle to the bicycle lane or its place, increasing its convenience; there are many ways to combine the carrying frame with the rear end of the vehicle, one of which is to fix a trailer ball at the rear end of the vehicle; Please refer to the seventh figure. A conventional structure (7) is the national patent certificate No. M319196, "Car at the end of the car, frame clamp ball clamp", which includes: a φ plug body (71), One end is a flange head (711) end and the other end has a threaded round rod, and the thread is predetermined to have a groove; a covering member (72) is formed in a bell-shaped upper end surface with a cylinder (721) The cylinder (721) is predetermined to have a U-shaped annular groove (722), and is equally divided into equal parts in the radial direction of the covering member (72), and the inside of the covering member (72) is packaged in the belly. One of the ball grooves (723) of the trailer ball is provided with an inverted inverted body (71). a bellows (724); a bell (73) 'with a chamber (731) in the abdomen and matching the entire shape of the cover (72), and the bell (73) The upper end surface is provided with a through hole (732) which is arranged in series with the plug body (71), and the predetermined 1324968 of the bell cover (73) is connected with one of the objects to be carried; a knob (74) ), by screwing the threaded end of the plug body (71) against the bell jar (73), and attaching a lock (741) that can limit the displacement of the knob (74); The aliquot (72) is wrapped with a flange head (711) of the inverted plug (71) and a trailer ball at the rear end, and then sequentially threaded through an inverted plug (71) Insert a bell (73) and attach a knob (74), and finally tighten the knob (74) to force the chamber (731) of the bell (73) to completely adhere to the cover ( 72) The 4 cover member (72) is fastened to the tow ball at the rear end of the vehicle. SUMMARY OF THE INVENTION (Technical problem to be solved) The above-mentioned conventional structure is to press the bell cover through the knob, and then press the cover member to cover the trailer ball, and the tail end of the car is combined and carried. The purpose of the frame is, however, that the force of the pressing force is limited to the vertical direction, and the bell-shaped cover can be prevented from moving up and down, but cannot effectively ensure that the bell-shaped cover is prevented from rotating along its axis, if The bell-shaped cover produces a rotational rotation, and the φ is deflected with the carrier frame, causing the risk of causing the vehicle to use the carrying frame. (Technical means for solving the problem) The present inventors have made a number of shortcomings in view of the above-mentioned conventional structure, and have begun research and development improvement, and finally developed the present invention: a rear end-carrying frame clamp ball clamp pressing device, which includes a a cover member, a bell cover and a knob, wherein the bell cover is provided with a connecting portion connected to the carrying frame, and the bell cover is pressed through the knob, and the bell cover presses the covering member to be wrapped a trailer ball that is pressed against the rear end of the vehicle, wherein the bell cover is provided with a groove corresponding to the connecting portion, and a lug is disposed on each side of the groove, and the lug is uniformly perforated for providing a quick release 6 1324968 The device extends through the through hole, and a cam edge of a hand provided on the quick release device abuts against the outer side of the lug, and then the cam is pressed to press the lug to reduce the cam The width of the groove is such that the bell is radially outward to urge the cover. SUMMARY OF THE INVENTION The main object of the present invention is to provide a gripping device for gripping a ball clamp of a rear end of a vehicle frame that does not deflect the carrier frame. A secondary object of the present invention is to provide a quick and easy operation of a vehicle-carrying frame clamp ball clamp pressing device. ® (cf. the efficacy of the prior art) As apparent from the above description, the present invention achieves the following effects compared to the prior art: 1. The present invention uses a different structure from the conventional structure to increase the bell shape from the horizontal radial direction. The force to tighten the cover member, and the thread outside the shaft of the quick release device is screwed into the internal thread of the lug during operation, so that the two sides simultaneously operate to press the lug to reduce the groove. The width, 俾, enhances the force of the bell to force the cover, causing the bell to ensure no deflection. 2. The invention utilizes the quick release principle, as long as the handle is rotated, the force can be quickly applied or unloaded to achieve the purpose of quick and easy operation. [Embodiment] Please refer to the first and third figures. The present invention relates to a rear end-carrying frame clamp ball clamp pressing device, which comprises a covering member (1) and a bell cover (2). a knob (3) and a quick release device (4); wherein, the cover member (1) is provided with a cylinder (11) on the upper end surface of the bell body, and the cylinder (11) is provided with a U a ring groove (12), and the covering member (丨) is equally divided into equal parts, and a ball groove (13) of the tow ball (5) covering the rear end of the covering member (1) is provided in the abdomen of the covering member (1) a socket (14) covering the flange head (151) of the inverted plug body (15) is also provided in the belly of the cylinder (11); and the plug body (15) is a flange head at one end ( 151) and a round rod having an external thread at the other end; the bell-shaped cover (2) has a chamber (21) in the abdomen and is matched with the corresponding covering member (1), and the bell-shaped cover ( 2) The upper end surface is provided with a through hole (22)' and the bell cover (2) is provided with a connecting portion (23) which is connected with a predetermined portion of the carrying frame and a groove is formed with respect to the connecting portion (23) (24) The section (24) is formed by a transverse groove (242) and a vertical section (241) is formed in a τ shape, and each of the two sides of the vertical section groove (241) is provided with a lug (25), and the lug (25) is provided with a perforation (251) for quick release device (4) extending through the through hole (251); the knob (3) ' is disposed in the body of the knob (3) is provided with a receiving groove (31), and a bottom end of the receiving groove (31) is provided The nut (32) is supplied to the specimen (15) φ, and the lock groove (33) is disposed adjacent to the accommodating groove (31), and the lock (33) is engaged with the plug body (15), The limit knob (3) is displaced, so that the lock (33) can prevent the thief from unscrewing the knob (3) and steal the function of the entire carrying frame; the quick release device (4) includes a handle (41), a turn Han (42), a loop (45) and a nut (44), wherein the shaft (42) is threaded through the through hole (251) of each lug (25).
