A concave part I1111 is arranged on the fastener I111, a concave part II 1121 is arranged on the fastener II 112, and an external device to be fixed (not shown) can be clamped in the concave part I1111 and the concave part II 1121. When the user releases the pressing on the fastener I111 and the fastener II 112, the distance between the fastener I111 and the second fastener 112 is increased again under the pushing of the elastic element 13 by the fastener I111 and the fastener II 112, and the external device to be fixed is clamped in the recess I1111 and the recess II 1121.

Further, referring to fig. 1 to 8, as an embodiment of the lock catch of the anti-theft lock according to the present invention, the elastic element 13 is a spring.

Further, referring to fig. 1 to 8, as a specific embodiment of the lock catch of the anti-theft lock of the present invention, a through hole i 1212 is formed on the first sidewall 121, and a through hole ii 1222 is formed on the sidewall ii 122; the buckle I111 is convexly provided with a protruding part I1112 inserted into the through hole I1212, and the buckle II 112 is convexly provided with a protruding part II 1122 inserted into the second through hole 1222. Therefore, the user can drive the first fastener 111 to move only by pressing the protrusion portion i 1112, or can drive the fastener ii 112 to move by pressing the protrusion portion ii 1122. If a user presses the first protrusion 1112 and the second protrusion 1122 in opposite directions, the first latch member 111 and the second latch member 112 can be moved relatively.

Further, referring to fig. 1 to 8, as an embodiment of the lock catch of the anti-theft lock provided by the present invention, a sliding slot 14 extending along the extending and retracting direction of the elastic element 13 is disposed on the outer surface of the first fastener 111, and a sliding block 1124 slidably disposed on the sliding slot 14 is disposed on the fastener ii 112.

Thus, the elastic element 13 sleeved on the fixing post 1113 is not easy to fall or shake.

Further, referring to fig. 1 to 8, as an embodiment of the lock catch of the anti-theft lock according to the present invention, a sleeve i 1114 is disposed on the first fastening member 111, a sleeve ii 1123 is disposed on the fastening member ii 112, one end of the elastic element 13 is connected to the inside of the sleeve i 1114, and the other end of the elastic element 13 is connected to the inside of the sleeve ii 1123. In this way, the inside of the sleeve i 1114 and the inside of the sleeve ii 1123 are respectively arranged outside the two ends of the elastic element 13, so that the two ends of the elastic element 13 are prevented from moving laterally (perpendicular to the stretching direction of the elastic element 13).

Further, referring to fig. 1 to 8, as a specific embodiment of the anti-theft lock catch provided by the present invention, a limiting block 1231 is convexly disposed on the bottom plate 123 between the first fastener 111 and the second fastener ii 112. Therefore, the limiting block 1231 can limit the maximum distance that the fastener i 111 and the fastener ii 112 can move on the bottom plate 123, so as to avoid the situation that the fastener i 111 or the fastener ii 112 is separated from the heat sink 12 due to the excessively large moving distance.

Further, referring to fig. 1 to 8, as a specific embodiment of the anti-theft lock catch provided by the present invention, a through hole iii 1232 communicating with the cavity is formed on the bottom plate 123, and the limiting block 1231 is protruded on an inner wall (not shown) of the through hole iii 1232. Therefore, the production of the limiting block 1231 is simple, the through hole III 1232 is firstly formed in the bottom plate 123, and then the limiting block 1231 is bent towards the inner side of the heat radiator 12. Of course, in other embodiments, the limiting block 1231 may also be directly fixed on the bottom plate 123, as long as the distance that the first latching component 111 and the second latching component 112 move on the bottom plate 123 can be respectively limited, which is not limited herein.

Further, referring to fig. 1 to 8, as an embodiment of the lock catch of the anti-theft lock according to the present invention, the first sidewall 121 is bent toward the inner side of the heat sink 12 to form a limiting portion i 1211 clamped in the recess portion i 1111; second sidewall 122 is bent toward the inside of heat sink 12 to form a stopper ii 1221 engaged with recess ii 1121. Thus, the first position-limiting portion 1211 is engaged with the first recess portion i 1111, and the second position-limiting portion ii 1221 is engaged with the second recess portion ii 1121, so that the first engaging member 111 and the second engaging member 112 are respectively engaged with the heat sink 12.

Further, referring to fig. 1 to 8, as an embodiment of the lock catch of the anti-theft lock of the present invention, the first position-limiting portion 1211 has a curved portion i 1213 slidably disposed on an inner wall of the recess i 1111, and the second position-limiting portion ii 1221 has a curved portion ii 1223 slidably disposed on an inner wall of the recess ii 1121. Therefore, when the fastener I111 or the second fastener 112 moves, the limiting part I1211 can be slidably arranged in the recess I1111, so that the first limiting part 1211 is prevented from blocking the movement of the fastener I111; similarly, the limiting part II 1221 is slidably arranged in the concave part II 1121, so that the phenomenon that the limiting part II 1221 obstructs the movement of the fastener II 112 is avoided.

Further, referring to fig. 1 to 8, as a specific embodiment of the anti-theft lock catch provided by the present invention, the anti-theft lock catch further includes a main body rail 15, the main body rail 15 has a rail side wall i 151 and a rail side wall ii 152 which are oppositely disposed, and a connecting plate 153 connecting the rail side wall i 151 and the rail side wall ii 152; the track side wall I151 bends towards the inner side of the main track 15 to form a limiting part III 1511 clamped in the concave part I1111; a limiting part IV 1521 clamped in the concave part II 1121 is formed by bending the inner side of the main body track 15 of the track side wall II 152. In this way, the main body rail 15 is clamped in the recess i 1111 and the stopper iv 1521 is clamped in the recess ii 1121 through the third stopper 1511, respectively, to fix the main body rail 15 to the fastener i 111 or the fastener ii 112. When the fastener I111 and the fastener II 112 move relatively, the distance between the concave part I1111 and the concave part II 1121 is shortened, the limiting part III 1511 and the limiting part IV 1521 are separated from the concave part I1111 and the concave part II 1121, and the main body track 15 is separated from the first fastener 111 and the fastener II 112; when the distance between the fastener I111 and the fastener II 112 is increased under the driving of the elastic element 13, the distance between the recess I1111 and the recess II 1121 is expanded, the third limiting portion 1511 is clamped in the recess I1111, and the limiting portion IV 1521 is clamped in the recess II 1121, so that the main body rail 15, the fastener I111 and the fastener II 112 are fixed to each other.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
