An octagonal support ring is fixed on a shaft roller and composed of eight support blocks distributed in an annular array on the support ring body; an insertion slot is formed on the support block; an insertion tenon is formed on an adjusting spoke; a layer of lint is fixedly stuck on the surface of the adjusting spoke; the insertion tenon is inserted and sleeved in the insertion slot; the right end of the adjusting spoke is in hinge joint with an adjusting rod; the other end of the adjusting rod is in hinge joint with an outer loop sleeve of a bearing; an inner loop sleeve of the bearing is fixed on the adjusting plate; the adjusting plate is inserted and sleeved on the shaft roller; one end of the adjusting plate is in hinge joint with a rack, and the other end is in hinge joint with a piston rod of a cylinder; a photoelectric probe is arranged below the adjusting spoke and detects a position signal of the cloth; the position signal is transmitted to a centering controller; and the centering controller sends an instruction signal to control the work of the cylinder. Before the cloth enters an edge guide device of the tentering setting machine, the cloth is centered to ensure that the cloth enters the edge guide device of the tentering setting machine from the center.

The invention relates to an elastic locating pin comprising an elastic pin, a pin seat, an adjusting bolt and a spring; the elastic pin is matched in the pin seat in a sliding mode and protrudes out of one end of the pin seat; the other end of the pin seat is fixedly provided with a limiting screw cap; the adjusting bolt is screwed in the limiting screw cap; and the spring is assembled between the adjusting bolt and the elastic pin. According to the invention, the limiting screw cap is additionally arranged at the end of the pin seat, when the elastic pin does not enter a locating hole of a workpiece, the limiting screw cap can stop the elastic pin from being pressed to the bottom, a worker can discover that the workpiece is not clamped in situ in time, in this way, the elastic pin can be enabled to enter the locating hole of the workpiece so as to locate the workpiece reliably.

The invention discloses a pile foundation type test well building method. The method comprises the following steps that 1, ground well drilling is performed through a drilling machine; 2, the drillingmachine is removed, a test outer well shaft is put down into a drilled well hole, and the position of the test outer well shaft is fixed; 3, a test inner well shaft is put down into the test outer well shaft; 4, a well mouth device is installed at the upper end of the test inner well shaft. According to the pile foundation type test well building method, the problems that an existing test well islong in building period, large in investment and not convenient to maintain and repair are solved.

The invention discloses a feeding device for a winding machine. The feeding device comprises a main framework. The main framework is adjacent to a winding device of the winding machine, and a fixing groove is arranged at the peripheral edge of the winding device. The feeding device is characterized in that a notching mechanism and a guiding mechanism are sequentially arranged on the main framework, a positioning groove can be punched on a to-be-wound steel belt by the notching mechanism, the steel belt can be guided into the fixing groove and positioned in the fixing groove by the guiding mechanism, and the positioning groove is matched with the guiding groove; the guiding mechanism comprises a guiding element, the guiding element is arranged on the main framework and can move relative to the main framework, a guiding groove is arranged in the guiding element, an inclination angle of the guiding groove is identical to an inclination angle of the fixing groove, and the shape of the guiding groove is matched with that of the steel belt; a through hole which is communicated with the guiding groove is formed in the upper portion of the guiding element, and a lower pressing piece capable of compressing the steel belt and the guiding groove is arranged in the through hole. The feeding device has the advantages that the winding machine is provided with the feeding device comprising the notching mechanism and the guiding mechanism, so that the steel belt can be precisely positioned to the upper side of the fixing groove of the winding device, and a starting end of the steel belt can be automatically fed into the fixing groove.

The invention discloses a statement-level Chinese and English mixed input method, which relates to an information input method, in particular to a Chinese and English mixed statement input method, and solves the problem that continuous sentence input cannot be ensured because which need to be converted into Chinese and which are English words in an input letter string are marked manually in the conventional Chinese and English mixed input method. The method comprises the following steps of: inputting a character string by using a keyboard; performing Chinese and English segmentation on the character string by using an input method management system, wherein the performed Chinese and English segmentation is automatic identification based on a Chinese pinyin library and an English word library; performing corresponding Chinese and English character conversion on the segmented character string and providing a mixed statement candidate and a Chinese and English word candidate by using theinput method management system, wherein the performed Chinese and English character conversion is the automatic identification based on a Chinese word library and a Chinese and English statistical library; selecting output contents from a candidate list finally by using the editing commands such as inserting, deleting, selecting and the like; and outputting a Chinese and English mixed statement. The method is used for character input.

The invention discloses an electric physical therapy hammer for treating muscular pain. The electric physical therapy hammer comprises a handle, a motor, a heat dissipation fan and a hammer body, wherein the motor and the heat dissipation fan are installed in a handle pipe hole and the hammer body is connected with the handle. The hammer body is of a hollow structure, a driving wheel, an eccentric wheel and a transmission rod are arranged in the hammer body, a rotation shaft of the motor is connected with the driving wheel through a coupler, an eccentric shaft is arranged at the end of the driving wheel, the eccentric shaft is sleeved with a rolling bearing to form the eccentric wheel, the eccentric wheel is installed in a connecting hole in the head portion of the transmission rod in a close-fit mode, and a beating head is connected to the top of the transmission rod. According to the electric physical therapy hammer for treating the muscular pain, circumferential motion of the rotation shaft of the motor is converted into up-and-down linear reciprocating motion of the beating head through the eccentric wheel, the beating head is used for conducting small-force high-frequency beating and mechanical vibration on muscles repeatedly so as to accelerate blood circulation, reduce lactic acid accumulation, break scar tissue into pieces and stimulate deep muscular tissue to accelerate injury recovery, and therefore the purse of treating the muscular pain is achieved.
