The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 5, a laser welder for eyeglass frame welding comprises a hand bracket 2 installed in an eyeglass frame laser welder 1;

two hand brackets 2 are symmetrically arranged and are positioned in a welding chamber of the glasses frame laser welding machine 1;

the hand bracket 2 comprises a base 21, a wrist bracket 22 and a finger bracket 23, wherein the wrist bracket 22 is arranged on the base 21 in a lifting way through a lifting component, and the finger bracket 23 is arranged on the side wall of the wrist bracket 22 in an adjustable way through a telescopic rod.

As shown in fig. 3 to 5, the lifting assembly comprises a lifting plate 221 and a clamping piece 27, the hand bracket 2 is rotatably installed on the lifting plate 221, the clamping piece 27 is installed at the bottom end of the lifting plate 221, the base 21 is provided with a slot 214, the side walls of the slot 214 are symmetrically provided with sliding grooves 211, the lifting plate 221 is located in the slot 214, and the clamping piece 27 is clamped in the sliding grooves 211.

As shown in fig. 3 to 5, a pressure spring 26 is further installed on the lifting plate 221, the pressure spring 26 is located above the clamping piece 27, a first clamping groove 271 and a second clamping groove 272 corresponding to the pressure spring 26 are formed in the clamping piece 27, the end portion of the pressure spring 26 is clamped in the first clamping groove 271 or the second clamping groove 272, a plurality of convex grooves are formed in the sliding groove 211, clamping posts corresponding to the convex grooves are formed in the end portion of the clamping piece 27, and the clamping posts are clamped in the convex grooves.

As shown in fig. 3, two ends of the sliding groove 211 are respectively provided with a first arc-shaped protrusion 212 and a second arc-shaped protrusion 213, a clamping column at the end of the clamping piece 27 slides through the first arc-shaped protrusion 212, the pressure spring 26 enters the first clamping groove 271 through the second clamping groove 272, the clamping column at the end of the clamping piece 27 slides through the second arc-shaped protrusion 213, and the pressure spring 26 enters the second clamping groove 272 through the first clamping groove 271.

As shown in fig. 3-5, the two ends of the sliding slot 211 are staggered in height, and two protrusions control the lifting or lowering of the clamping column at the end of the clamping piece 27, because the pressure spring 26 always applies pressure to the first clamping slot 271 of the clamping piece 27, when the lifting plate 221 is pulled, the lifting plate 221 moves upwards, the clamping piece 27 lifts upwards along with the convex slot, because of the pressure spring 26, when the clamping column slides to the ends of the two convex slots, the pressure spring is still located in the first clamping slot 271, when the clamping piece 27 slides to the top of the first sliding slot 211, the clamping column is jacked upwards by the second arc protrusion 213, at this time, the pressure spring 26 slides to the second clamping slot 272 in the first clamping slot 271, at this time, the clamping column is lifted and cannot be clamped in the convex slot of the sliding slot 211, when the lifting plate 221 slides to the bottom, the clamping column is pressed downwards by the first arc protrusion 212, at this time, the pressure spring 26 enters the first clamping slot 272 in the second clamping slot 271, recovering the pressure state;

therefore, the height of the lifting plate 221 can be adjusted through the matching of the clamping piece 27 and the pressure spring 26, a good supporting effect can be achieved, and the height of the hand bracket 2 can be adjusted according to the comfort of a user.

As shown in fig. 3 and 4, the telescopic rod comprises two extending rods 24 and two fixing rods 25, each extending rod 24 and each fixing rod 25 form a group, the diameter of each fixing rod 25 is larger than that of each extending rod 24, one end of each extending rod 24 extends into each fixing rod 25, the other end of each fixing rod 25 is fixed on the side wall of the wrist bracket 22, and the finger bracket 23 is mounted at the other end of each extending rod 24.

As shown in fig. 3, a mounting hole 232 corresponding to the diameter of the fixing rod 25 is formed in the side wall of the finger rest 23, one end of the extension rod 24 is fixed in the mounting hole 232, and one end of the fixing rod 25 extends into the mounting hole 232.

Finger bracket 23 can be installed on wrist bracket 22 by pulling, when not using, or when the operation is improper, can withdraw finger bracket 23, through little finger in finger groove 231, with finger bracket 23 hook back, dead lever 25 this moment pegs graft in mounting hole 232, and extension rod 24 pegs graft in dead lever 25, realizes contracting, saves space.

As shown in fig. 2 to 4, a finger slot 231 is provided on the top surface of the finger rest 23.

The finger groove 231 is used to place fingers to prevent the hand from shaking to cause erroneous welding when holding the glasses frame, so that the small finger is placed in the finger groove 231 of the finger rest 23 to make the hand more stable by supporting the finger.

Above-mentioned structure does not improve spectacle-frame welding laser welding machine, has only increased the hand saddle in laser welding machine's welding chamber, prevents because the weld time is of a specified duration, perhaps the hand is unstable, causes the welding error, leads to the spectacle-frame to damage, perhaps the problem that can't sell beautifully causes economic loss.

The concrete structure is as follows:

a welder puts two hands into a cavity of the spectacle frame laser welder 1, puts a wrist on the wrist bracket 22, feels comfortable, and adjusts the height of the wrist bracket 22, when the wrist bracket 22 is felt to be low, the wrist bracket 22 is lifted, the wrist bracket 22 drives the lifting plate 221 to slide in the base 21, the clamping piece 27 is clamped on the convex groove of the sliding groove 211 to reach a proper height, when the height is increased and the wearer is uncomfortable, the wrist bracket 22 needs to be pulled to the top end, so that the clamping column on the clamping piece 27 is jacked up by the second boss, the pressure spring 26 is clamped in the second clamping groove 272, and the second clamping groove 272 is pressed down to the bottommost part for readjustment;

after the height is adjusted, welding is carried out, during welding, a wrist is put on the wrist bracket 22, the wrist presses downwards, the clamping piece 27 at the moment is clamped in the convex groove of the sliding groove 211, the clamping column is stably clamped in the convex groove due to the pressure of the pressure spring 26 and the pressure of the wrist, then fingers are put in the finger groove 231 on the finger bracket 23, and the finger bracket 23 can be pulled randomly according to the distance and the size of the picture frame held by the hand until the finger bracket 23 reaches a proper position;

the control switch in the welding chamber, as well as the welding head, are known in the art and will not be described in detail here.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
