New description: [New technical field] This creation is related to a stop structure of a rotating shaft, especially a stop structure that can limit the angle of rotation, and is suitable for a folding electronic device. [Prior Art] The prior art, such as the new patent of the Republic of China Announcement No. M303606, which can limit the angle of the pivoting device, is disposed between the display screen and the body of the folded electronic product, and includes: a base 'solid Connected to the body of the folded electronic product, and provided with a circular hole, the lower surface of the circular hole forms a stopper; a support frame is fixed to the display screen of the folded electronic product; and a rotating shaft has a connection with the support frame And a shaft portion passing through the circular hole of the base; a spring piece group is disposed on the shaft portion of the rotating shaft and provides a pressing force in the axial direction of the rotating shaft; and a friction wheel group is disposed on the shaft portion of the rotating shaft to generate The resistance enables the support structure fixed on the display screen of the folded electronic product to be folded or angularly opened relative to the body of the folded electronic product; and the stop cam has a perforation for the shaft portion of the rotating shaft to pass through together Rotating and having a scallop on the outer edge, the side of the stop cam sector will contact the stop below the hole of the base to achieve a stop when the shaft rotates, and the hinge can be defined. The above-mentioned prior art block is provided on the base. Due to the thin thickness of the base, the structural strength is insufficient, and the strength of the broadcast block is insufficient. When a large electronic device such as a notebook computer displays a screen turn, Lin stop block (four) block is reported to be large, easy to damage after repeated use, and the joint between the block and the base is easy to break, resulting in poor stop effect, even losing the stop function. And because the side plate of the base should be set The hole for the shaft to be threaded, M3 51960 has a hook for the fixed wheel to be inserted into the fixed hole, and several oil holes, and to avoid the line through the base, so a convex shape is formed on the base. The stopper is used to match the stop cam, and the strength is also required. There is a space problem. [New content] The main purpose of the creation is to provide a stop structure of the rotating shaft, which is the first to be mutually fitted. The blocking member and the second locking member are provided with stoppers that stop each other to increase the strength of the stop, the strength of the stopper is high, and it is not easy to be damaged, and the service life of the rotating shaft can be improved. To achieve the above purpose, the technical means adopted by the creation is The utility model comprises: a set of sockets and a boring hole. A mandrel is pivoted on the boring hole by a limiting shaft. A first locking member and a second locking member are sequentially sleeved on the limiting shaft a rod, and a contact surface thereof is provided with at least one pair of positioning grooves and positioning protrusions which are mutually engageable, and at least one pair of stoppers which are mutually stopable. The first blocking member is sleeved on the pivoting hole Limiting the shaft, and the set of the base is provided with a fixing hole, the first locking member is convexly provided with a positioning post and is fixed to the fixing hole, and the second locking member has the same section as the limiting shaft The limiting hole is sleeved on the limiting shaft to rotate synchronously with the mandrel. When the screen of the folding electronic device is opened, the mandrel rotates and drives the second locking member to rotate synchronously, and when the cock is turned to the limiting angle, the second The block of the latching member blocks the stop of the first latching member to limit the angle of rotation of the screen. The first latching member and the second latching member have high structural strength, and the blocking member has strong binding force and is not easily damaged. . Another technical approach taken by this creation consists of: M351960 A set of sockets with a boring hole. A mandrel is disposed on the pivot hole by a limiting shaft frame. a first locking member and a second locking member are sequentially sleeved on the limiting shaft, and the contact surface is provided with at least one pair of positioning grooves and positioning protrusions that can be fitted to each other, and at least one pair can mutually The stop of the stop, the other side of the first latching member is provided with a stop piece, the stop piece is convexly provided with a stop portion, and the other side of the first lock piece is convexly provided with a second stop The activity is limited to the second block. The first latching member is sleeved on the limiting shaft by a pivoting hole, and the set of the latching member is provided with a fixing hole, and the first latching member is convexly disposed with a positioning post embedded in the fixing hole; the first latching member And a limiting hole having the same section as the limiting shaft of the limiting piece is sleeved on the limiting shaft to rotate synchronously with the spindle. When the screen is opened, the 'the spindle rotates and drives the second latch and the stop plate to rotate synchronously'. When the turn is turned to the closed angle, the load block (four) of the second lock member stops at the stop of the first lock member and stops The file section of the cymbal block is blocked by the second broadcast block, so that the stopping strength is higher and the supporting force can be improved. The present invention will be further described below in conjunction with the drawings and specific embodiments. [Embodiment] Please refer to the 1st to 3rd, which is a three-dimensional diagram of the exfoliation-actual age egg, the component exploded view, and the -th and second parts.
